Known for his irrepressible mischievous grin, Jimmy Fallon (and his silliness) have revived The Tonight Show franchise like never before. His off-the-wall games with celebrities and his musical shenanigans — most recently with Barbra Streisand — make headlines almost on a weekly basis.

Whether he's tapping into his inner Elvis with Babs, slow jamming with President Obama, or throwing balls at Julia Roberts's face, Fallon seems to take his silly advice quite seriously, don'tcha think?
